10 GPM Through 200' x 3/8" Hose

We have run 1000 ft 3/8 on some jobs with around 2000 psi in the past. Overall pretty happy with the 1/4 inch when was can use it.

Changed as in lowered pressure?

Bumping this one because the hose question comes up every time somebody moves up to a bigger machine.

Short answer. You keep your flow. You lose pressure. The longer and smaller the hose, the more pressure you lose.

  • Pull up a hose friction loss chart from your pump or hose maker. It shows the loss for your gpm and hose size.
  • Put a gauge at the gun one time. Then you know what you really have at the surface, not what the machine says.
  • Size your nozzles for the pressure at the end of the hose, not at the pump.
  • Like the guys said, a lot of contractors run 1/2" off the reel and 3/8" on the last section so it's easy to drag.
  • If your unloader is dumping a lot of water into bypass, something is too small. Check the tip and the hose.
  • Only run as much hose as the job needs. Move the rig closer when you can.

On flatwork and rinsing, flow is what does the work. Don't choke it off with the wrong hose.
